Most of mine just go to the right. I swapped sensors around in a confusing manor and got 2 to center. These thing are awful to get right. I like the design. However the P3 cameras are easier to fix. Maybe because there are lots of parts other than the main board. The P4 has a pretty good main board but the sensors are impossible to find. I have worked on about 10 of the P4's and have never had a bad main board assembly. It is almost always a Yaw problem. usually goes to the right when facing the camera
